• For a triangle - 2D element consisting of 3 nodes a the Aspect - Ratio is calculated as the ratio of the length, h2, of the edge - of this triangle, to the height, h1. The ratio of h2 to h1 is then multiplied - by  3(1/2) /2, so that - a Â“perfectÂ” element in the shape of an equilateral triangle will be equal - to 1. This procedure is repeated for the remaining two edges of the triangle, - and the largest value is retained as the Aspect - Ratio for the element.
